Trapped in a stale marriage and buried in work, a lonely husband secretly hires an escort every payday. After receiving a bonus, he splurges on an option promising a blowjob within five seconds of meeting. A curvy G-cup escort named Maki arrives at the hotel wearing erotic lingerie under her coat, immediately sucks him off, and swallows his load. But once they reach the room, he realizes she is actually Riho, his best friend's wife. She admits that her husband no longer has sex with her and that frustration drove her into escort work. In return for his silence, she buries his cock between her lotion-covered breasts and gives him an intensely slippery titjob. Later, Riho invites him to dinner at her home and secretly offers the intercourse that had been off-limits before. Desperate to be fucked, she climbs on top, rides him wildly, and grinds him deep inside until he cums in her. Fully consumed by lust, Riho takes control, toys with him, and drains him completely.
